Design Master Wish List

The current releases are DM Electrical RT 1.1, DM Electrical 8.4, DM HVAC 7.3, and DM Plumbing 4.1. We are not adding new features to these releases.

The next releases will be DM Electrical RT 1.2, DM Electrical 8.5, DM HVAC 7.4, and DM Plumbing 4.2 We are actively working on these release and using this wishlist to guide which features we implement. Some features you see marked as “complete” will not be available until these releases are finished.

How can we improve Design Master?

You've used all your votes and won't be able to post a new idea, but you can still search and comment on existing ideas.

There are two ways to get more votes:

When an admin closes an idea you've voted on, you'll get your votes back from that idea.

You can remove your votes from an open idea you support.

To see ideas you have already voted on, select the "My feedback" filter and select "My open ideas".

Enter your idea

(thinking…)

Enter your idea and we'll search to see if someone has already suggested it.

If a similar idea already exists, you can support and comment on it.

If it doesn't exist, you can post your idea so others can support it.

There may already be an option (please inform me as I am not aware) for a 'duct continuation symbol/fitting'. Currently I have to go back and Pline a goofy looking thing to indicate continuations in the ductwork. Any thoughts?

Add capability to have custom two line callouts for supply, return and exhaust diffusers as there is currently for one line callouts. Allow the second line to be blank for the return callout as there is often no need for cfm on the return callout. Same as a two line callout for supply diffusers and one line for return grilles.

The pressure drop calcs indicate the wrong fitting types in some cases. For example, a fitting that begins with "SD" stands for "Supply/Diameter" and "SR" stands for "Supply/Rectangular", etc. If you have a duct system that is all rectangular, there should not be any SD fittings indicated. Likewise for round systems, there should not be any SR fittings indicated.

In the "Room Project Schedule" add a box which would allow for the addition of design notes. This would allow for the designer to document why certain values where chosen. When the loads are printed the notes would also be displayed for reference.

Currently to view the ventilation and load schedules the report is run and appears in an html file. If for instance the outside air % is too high I then have to exit the report go back into the rooms with the high percentage and manually overventilate.

It would be great if there was a screen that combined all of the room information, areas, CFMs, etc. (similar to the load report) but this screen allowed you to manually modify the CFMs, system static pressure, outside air percentage, etc. and by doing this all of the room information is updated at the same time. This would allow you to tweak the loads if need be and as this is being done the cooling and heating loads are updating as well. This would save a lot of time when viewing the loads.

Also, something similar to room inputs could be helpful as well. Input all of the roomnames in a sort of a spreadsheet and have the button to draw the room and store the floor area, room area, etc. right next to the roomname. All of this information is being stored somewhere but it would probably involve changing how the information is formatted and may be too big of a task.

Modify design load calculations to more accurately size/select VAV boxes. The revised calculations would take into account the heat required to overcome the additional air supplied to the VAV box that is over and above the minimum required in the heating calculations. This will help since the additional air is typically at 55 degrees and will actually add heat load to the space in addition to that required by the envelope and minimum supply air. In some cases this can be a significant load.

Using the maximum scheduled pressure drop for every scenario over inflates the pressure calcs. This is very important for low-pressure systems with low static terminal units such as ducted VRF and Fan Coil Units that max out at .25". Using the maximum scheduled pressure drop of say, .1" for air devices make it difficult to design low static systems accurately.
